Nanny state here we come. When the gubmint starts charging for
rescues, then the rescued will start demanding perfect performance from the rescuers, which in turn will demand restrictions of our activities for our own safety and their
reduction of liability.

No more solo hikes, hang gliding, climbing etc. And for those
considering insurance for those activities? Exemptions. If
you are found liable by the rescuers, you can be sure the
insurance companies aren't going to pay for your costs either.
